Question

A truck cover $224km$ in $4hours$, the average speed of a bike is $\frac{1}{4}th$ the average speed of the truck how much distance will the bike cover in seven hours?.

• A. $96km$
• B. $98km$
• C. $95km$
• D. $92km$

Answer 1

Answer: (B)

$98km$

Truck covers $224km$ in $4hours$

So,

Speed of truck $=\frac{224}{4}=56kmph$

As speed of bike is $\frac{1}{4}th$ the speed of truck

So,

Speed of bike $=\frac{1}{4}\times 56$

$=14kmph$

Distance covered by bike in 7 hours $=14\times 7$

$=98km$
