average speed = total_distance/total_time = (80 km + 100 km)/(10 min + 20 min) = 180 km/30 min = 6 km/min 1 hr = 60 min → 6 km/min = 6 × 60 km/h = 360 km/h
Average speed = Distance/Time = 2.5 miles/15 minutes = 10 miles per hour
depends on your speed... It depends on how fast you drive. If you average 51.8 miles per hour it will take 10 hours.
Average speed is total distance divided by total time. Hence 10 metres in 6 seconds is an average speed of (10/6) = 2.66666 m/s. Notice the units of speed - if you ever forget that speed is distance over time, just remember speed's units is something like metres per second, miles per hour etc. "per" means divided by.
Shane's mother's average speed is 6.7 MPH. 10 miles/ 90 minutes = 1/9 miles/minute 60 minute/hour 1/9 miles/minute x 60 minutes/hour = 6 2/3 miles/hours 6.7 mph
When you walk a distance of 2 km in 10 minutes your average speed is 0.2 km per minute.
One mile per ten minutes is six miles per hour (average speed). ============= Solution Method: ----------------- There are 60 minutes in 1 hour. We often say there are 60 minutes per hour. We express this relationship mathematically as: 60 min/hr To convert miles/min to miles/hr, do the following: 1 mile/10 min * 60 min/1 hr = 60 / 10 = 6 miles/hr (average speed) * Note: minutes cancel in the numerator & denominator).
If you go 2 miles in 5 mins and then 2 miles in 10 mins, you have gone 2 + 2 = 4 miles in 5 + 10 = 15 mins 60 min = 1 hours → 15 min = 15/60 hr = 1/4 hr speed = distance ÷ time → speed = 4 miles ÷ 1/4 hr = 4 × 4/1 mph = 16 mph.
5 mi /(10 min/60 min/hr) = 30MPH.
Your average speed is 10 miles per hour.
If someone runs 10 miles in 90 minutes their average speed is 6.67 mph
He drove 20 miles in 50 min. so average was 20 x 60/50 = 24 mph
To find average speed, divide the total distance by the total time taken. Total time = 2 hours + 10 minutes = 2.167 hours Average speed = 720 miles / 2.167 hours ≈ 332.25 miles/hr.
Your avarage speed would be 12 miles an hour.
Her average speed is 6.67 miles per hour (10 miles in 90 minutes is the same as 6.67 miles in 60 minutes).
At 60 MPH average, about 6 minutes.
At 60 MPH average, about 4 hr 10 min.
