The cyclist's average speed in mph = 24140.1 mph
Explicație pas cu pas:
2 miles in 10 minutes, this means that he will travel 12 miles in 60 minutes.
12 miles converted in meters: 12x1609.34= 19312.08 metres.
The first speed: V = 19312.08 mph
6 miles in 20 minutes, this means that he will travel 18 miles in 60 minutes.
18 miles converted in meters: 18x1609.34=28968.12 metres.
The second speed: V = 28968.12 mph
The average speed = (the first speed + the second speed)/2
The cyclist's average speed = (19312.08+28968.12 )/2
= 24140.1 mph
