Question

A car travels 210km in three 1 by2 hr then find
1. how much time is required to cover 60km with yhe same speed.
2. The distance covered in 5 hrs with the same speed.

Answer 1

HEYA MATE, HERE IS UR ANSWER

$<b><i>First we need to find at what speed car is travelling$

Distance covered =210 km

Time =3$\frac {1}{2}$

Time=$\frac {7}{2}$ hr

Speed of the car=$\frac{distance}{time}$

=210÷$\frac{7}{2}$

=$\frac {210×2}{7}$

= 60 km/hr

So,the car is moving with speed 60 km/hr .

Case 1

Distance =60 km

Time=?

Speed=$\frac {distance}{time}$

60=$\frac {60}{time}$

60 ×time=60 ---[by cross multiplication]

time=$\frac {60}{60}$

time=1 hr .

So the car will take 1 hour for travelling distance of 60 km .

Case 2.

Speed=60 km/hr (same)

Time=5 hours

Speed=$\frac {distance}{time}$

60=$\frac {distance}{5}$

60×5=distance[by cross multiplication]

300=distance

So the car travels 300 km in 5 hours.
