Question

A car covers 130 kilometres at a constant speed in 2 hours along a highway. How much distance
will the car cover in 4.5 hours at the same speed? in ratio

​

Answer 1

Step-by-step explanation:

Given: Distance covered in 2 Hours = 130 Km

To Find : Distance covered in 4.5 Hours =

Here,

We know that

Speed = Distance / Time

Therefore,

s1 = d1 / t1

s2 = d2 / t2

but it is given that,

s1 = s2. ________ speed is constant.

130 x 100 / 7200 = d2 / 17400

13000 / 7200 = d2 / 17400

130 / 72 = d2 / 17400

65 / 36 = d2 / 17400

1131000 / 36 = d2

d2 = 31416.6 m

d2 = 31416.6 / 100 km

d2 = 314.16 km

Hence distance travelled in 4.5 hours is 314.16 km
