Question

A bus travel's 440 km in 8 hrs
(I). How long will it take to travel 385 km
( ii ) how far will it travel in 6 1/2 hour

Answer 1

Speed of bus = 440/8 km/hr
= 55 km/hr

i ) Distance = 385 km
Speed = 55 km/hr

Time = Distance / Speed
= 385 km ÷ 55km/hr
= 7 hours.

ii ) Time = 6 1/2 hrs
= 13/2 hr
Speed = 55 km/hr

Distance = speed × time
= 13/2 hr × 55 km/hr
= 357.5 km.

Answer 2

Answer:

(i) 7 hours (ii) 357.5 km

Step-by-step explanation:

Formula needed:

1. Speed = Distance ÷ Time

2. Time taken = Distance ÷ Speed

3. Distance = Speed x time

STEP 1: Find the speed of the bus

Speed = Distance ÷ Time

Speed = 440 ÷ 8

Speed = 55 km/h

STEP 2: Find the time needed to travel 385 km (Question (i) )

Time taken = Distance ÷ Speed

Time taken = 385 ÷ 55

Time taken = 7 hours

STEP 3: Find the distance traveled in 6 1/2 hour (Question {ii) )

Distance = Speed x time

Distance = 55 x 6 1/2

Distance = 357.5 km

Answer: (i) 7 hours (ii) 357.5 km
