Answer:
4 hours and 7 hours
Step-by-step explanation:
Marcus = x hours
Donnell = x + 3 hours
Total = 11 hours
- x + x + 3 = 11
- 2x + 3 = 11
- 2x = 8
- x = 4
So Marcus practiced 4 hours and Donnell practiced 7 hours
40 miles an hour
60 [minutes] * 60 [seconds]= 3600
22.5[seconds for 1/4 of a mile]* 4[ one mile]= 90 [seconds per mile]
3600/90=40 [miles an hour]
You'll reach destination in 1.6 days or rounded to 2 days.
->calculate how much did you pass already 1250×5/7=892 miles traveled (rounded)
->then calculate how much miles you have to go
1250-892=358 miles left to travel
->then calculate speed at which you travel
892/4(how much days you traveled already)=223miles per day
->then just divide miles left with speed
358/223=1.6 or 2 days left to reaching destination.
