Question

A car covers 350 km in 7 hours how much distance it will cover in 10 hours.

Answer 1

Answer:

It will cover a total distance of 496.8kilometers

Step-by-step explanation:

Before calculating, let us first convert the values to base units;

Given Data:

• Distance Travelled in case 1 = S1 = 350km = 350,000metres
• Time taken in case 1 = t1 = 7hours = 7x60x60seconds = 25,200seconds
• Time Taken in case 2 = t2 = 10 hours = 10x60x60 seconds = 36,000seconds

To find:

• Distance Travelled in case 2 = ?

Solution:

We know that;

Distance = velocity x time

or S = vt

so, v = S/t

Using Case-I values to first calculate velocity:

v = 350,000/25,200

v = 13.8m/s

Now, calculating Distance in CASE-II by using the value of v as;

S = vt

Putting values,

S = 13.8 x 36000

S = 496,800metres

S= 496.8 kilometres
