michelle and themba are travelling from cape town to Johannesburg by car. they travel 30km in 18 minutes and continue at a constant speed. how far will they have travelledin 1 hour 24 minutes?
Answers
Answer:
If they travel
30km in 18mins
then , speed = distance(km)/ time(hr) ; 60mins=1hr , 1min=1/60hrs
18mins=18×1/60hrs=3/10hrs
speed=30/(3/10)km/hr =100km/hr
1hr 24mins = 1+[24×(1/60)] mins = 1+ 4/10=14/10
distance=speed/time=100/(14/10)=1000/14=500/7= 71.4 km
If they maintain a constant speed the entire way, Michelle and Temba would have covered 140 km in 1 hour and 24 minutes.
The following equation can be used to determine the average speed of Michelle and Temba:
Distance x time speed
They covered 30 kilometers in 18 minutes, so their average speed is:
speed = 30 / (18 / 60) = 30 / 0.3, or 100 km/hr.
They would have traveled the following distance in 1 hour and 24 minutes, or in 1 hour + (24 / 60) hours, or 1.4 hours:
The distance= speed * time, or 100 * 1.4 = 140 km.
Therefore, it is important to remember that their speed and the actual distance they travel can be impacted by real-world variables like traffic, road conditions, and vehicle maintenance.
