Question

A car travels a distance of 550 km in 5 hours.
(a) What distance will the car cover in 7 hours?

(b) How many hours are needed to travel a distance of 3080 KM if the car travels at a uniform speed?​

Answer 1

a)5hr=550km

So,

1hr=550/5km=110km

So,

7hr=110×7=770km

So, the car will travel 770km in 7

hours.

b)110km=1hr

So,

3080km=1/110×3080hr=28hr

So, the car will take 28 hours to

cover 3080 km.

• (a) What distance will the car cover in 7 hours?

We have,

Distance travelled by the car is 5 hrs:

= 550 Km

Distance travelled by the car in 1 hour:

= 550 Km ÷ 5

➠ 110 Km

Distance travelled in 7 hours:

= 110 Km × 7

➠ 770 Km

• Hence, distance travelled in 7 hours = 770 Km.

We have,

Time taken to travel 550 km:

= 5 Hours

Time time taken to travel 1 km:

= 5/559 hours

➠ 1/100 hours

Time taken to travel 3080 km:

= 3080 × 1/100

➠ 28 Hours

• Hence, time taken to travel 3080 km= 28 Hours.
