Kruka [31]

Given :

Peter velocity , P = 30 mph .

Mitchell velocity , M = 40 mph .

Mitchell leaves 15 min later .

To Find :

If they drive along the same route how long will it take Mitchell to catch Peter.

Solution :

Distance covered by Peter in 15 min .

$D = 30\times \dfrac{15}{60}=7.5\ miles$

Let , time taken is x .

So , distance covered b them is equal :

$7.5+30\times x=40\times x\\\\x=\dfrac{7.5}{10}=0.75\ hours\\\\x=0.75\times 60\ min\\\\x=45\ min$

Therefore , time taken by them is 45 minutes .

Hence , this is the required solution .
