-6
Step-by-step explanation:
Answer: the cyclist must wait for 25 minutes until the hiker catches up.
Step-by-step explanation:
Distance = speed × time
The Cyclist was travelling in the same direction along the same path
as the hiker at a constant rate of 20 miles per hour. If the cyclist stops to wait for the hiker 5 minutes after passing her, then the distance that the cyclist travelled in 5 minutes(5/60 hour) is
20 × 5/60 = 100/60 miles
For the hiker to catch up with the cyclist, she would cover 100/60 miles at a speed of 4 miles per hour.
Time = distance/speed
Time required by hiker to catch up with the cyclist is
(100/60)/4 = 100/240 hour
Converting 100/240 hour to minutes, it becomes
100/240 × 60 = 25 minutes
Answer:
Andrew will do 7 1/2 + 7 1/2 which equals 15
Step-by-step explanation:
Hope it helps
Im not completely sure that its right...
280 = 20x + 100
20 * 9 = 180
x = 9
Check you answer :
280 = 20 ( 9 ) + 100
280 = 180 + 100
280 = 280 . True statement
