Answers
Answer:
(i) 1.5 hrs
(ii) 150 km
Step-by-step explanation:
Given: Distance = 90km
Time = 3 hrs
Speed = ?
to find speed;
speed = dist./time
speed = 90/3
speed = 30 km/hr
(i) to find time;
time = dist./speed
time = 45/30 [speed is constant throught the journey]
time = 3/2
time = 1.5 hrs
(ii) to find distance;
dist. = speed X time
dist. = 30 X 5 [speed is constant throught the journey]
dist. = 150 km
