It would be 8 miles
4.70 km walked in 50 minutes equates to 3.5 miles per hour.
1 hr = 60 mins time = distance ÷ speed = 8 miles ÷ 80 miles/hour = 0.1 hour = 0.1 x 60 mins = 6 mins.
3 miles = 20 mins ? miles = 60 mins Ans = (60/20)*3 = 3 * 3 = 9

4.70 km walked in 50 minutes equates to 3.5 miles per hour.
21 miles / 21 minutes, x 60 (mins per hour) is 60 miles per hour
It is 148000 miles per hour.
1 hr = 60 mins time = distance ÷ speed = 8 miles ÷ 80 miles/hour = 0.1 hour = 0.1 x 60 mins = 6 mins.
The time of 20 mins is multiplied by 3 to get to the 'per hour" so car travels 18 miles times 3 = 54 miles per hour the answer is 54 mph
1 hour and 30 mins
2 hours, 7 mins, 30 secs
15 (m/s) x 60 (secs) x 60 (mins) = 54000mph
3 miles = 20 mins ? miles = 60 mins Ans = (60/20)*3 = 3 * 3 = 9
378 / 70 is 5.4 hours or 5hrs 24 mins.
