Question : 75 of 100

Marks: +1, -0

A car covered

150 {\km}

5 {\h}

. If it travels at one-third its usual speed, then how much more time will it take to cover the same distance?

Solution:

According to the question,
Speed of the car

={150}/{5}=30 {\km} \/ {h}

.
If speed

={1}/{3} ×30=10 {\km} \/ {h}

∴ Time required to cover some
distance

={150}/{10}=15 {h}

∴ Extra time

=15-5=10 {h}
