Liam biked for 3 hours at a speed of 8 mph and then walked the remaining part of his way at a speed of 3 mph. If the total dista
nce he covered was 30 miles, how much time did he walk?
1 answer:
Answer:
2 hours
Step-by-step explanation:
First we need to know the distance Liam travelled using the bike.
If his speed was 8 mph and he travelled 3 hours, the distance travelled by bike is:
d = 8 * 3 = 24 miles
The total distance is 30 miles, so the remaining is:
30 - 24 = 6 miles
He travelled 6 miles with the speed of 3 mph, so the time walking is:
time = 6 / 3 = 2 hours
