Answer 1

Answer:

★ (i) Time taken = 8 hours ★

★ (ii) Distance travelled = 455 km ★

Step-by-step explanation:

Given:

• A car travels 195 km in 3 hours.

To find:

• (i) How long will it take to travel 520 km ?
• (ii) How far will it travel in 7 hours with same speed ?

Solution:

(i)

$\implies$ Time taken for 195 km = 3 hours

$\implies$ Time taken for 1 km = 3/195 hours

$\implies$ Time taken for 520 km = (3/195)×520 = 8 hours

Hence, it will take 8 hours to travel 520 km.

(ii)

$\implies$ Distance covered by car in 3 hours = 195 km

$\implies$ Distance covered by car in 1 hour = 195/3 km

$\implies$ Distance covered by car in 7 hours = (195/3)×7 = 455 km

Hence, it will travel 455 km in 7 hours with same speed.
