2018 Test B Math · Question 40 of 57

On a bike trip, Rajiv traveled 65 kilometers in 5 hours, while Shaina traveled 72 kilometers in 4 hours. How much less was Rajiv’s mean speed, in kilometers per hour (kph), than Shaina’s?

Show the answer

Correct answer: B

Calculate each mean speed:

$R=frac{65}{5}= 13kph$

$S=frac{72}{4}= 18 kph$

Then calculate the difference of both mean speeds:

$S-R=18-13=5kph$
