Question

A motor boat travels at a speed of 20 kilometers per hour. How long will it take to go 85 kilometers

Answer 1

Here,

• Speed = 20 km/h
• Distance = 85 km

We know that,

Speed = Distance/Time

Substitute the given values. We get,

Time = 85/20

⇒ Time = 4.25 hours.

Therefore,

It will take 4.25 hours.

$\rule{200}2$

Answer 2

ANSWER:-

➣

• Given:-

${Speed [s]= 20 km/hr.}$

${Distance [d]= 85 km}$

•To find:-

${Time = ?}$

• Formula:-

$\bf{Speed={\frac{Distance[d]}{Time[t]}}}$

SOLUTION:-

• Using the above Formula:-

$\bf{Time={\frac{Distance[d]}{Speed[s]}}}$

$\longrightarrow{Time ={\frac{85}{20}}}$

$\longrightarrow{Time={\cancel{\frac{85}{20}}}}$

$\longrightarrow{Time=\bf{4.25 hrs.}}$

➣

Therefore, it will take $\bf{4.25 \ hours}$ for the motor boat to go to $\bf{85 \ km.}$
