For this problem, you would use the formula distance =rate x time. You have the distance traveled, 2.4 miles. You have the time it took to travel that distance, 135 minutes. Now, you want to know the rate (how fast) it took to swim that distance.
d = rt
Now let's fill in your information
2.4 miles = r x 135 minutes
The first step is to convert 135 minutes into hours, so the answer will result in miles per hour (mph). 135 minutes divided by 60 minutes equals 2.25 hours. Let's rewrite the equation
2.4 miles = r x 2.25 hours
2.4 miles/2.25 hours = r
1.06 miles/hour = r
So, if someone swam 2.4 miles and it took them 135 minutes, the swimmer was swimming at 1.06 mph.
27.9 miles per hour
130.6 miles per hour.
30.94 mph
26.7 mph
120 mph
they travel 200 miles an hour when swimming their fastes speed
27.9 miles per hour
60 miles an hour.
80 miles per hour.
130.6 miles per hour.
54 miles in 22 minutes = 54*60/22 = 147.2727.. miles per hour
66.7 mph
21124 mph
381.82 mph
30.94 mph
26.7 mph
120 mph
