11. Grace rides her bike 41 miles with a constant speed of 12 mph and another 36 miles with a constant speed of 12 mph, What is her average speed for the total trip?
Answers
Answer:
Two different units of measure for time are used - hours and seconds. To continue on must be changed to the other.
20 minutes = 20/60 hour
= 1/3 hour
Distance = rate · time
d = 12m/h · 1h/3
d = 4m
You rode 4 miles.
Answer:
0.3miles/hour
Step-by-step explanation:
the time is not given to us so first we have to find that so for that its 41+36/12which is 77/12 hours so we have to convert it in minutes now because its in fraction so we will multiply it by 60 so 77/12x60 which will give us 385 minutes so now we can find out our speed which will be distance/time=77/385 which will result in us getting 0.2miles/minute but we have to get miles/hour so for that we will simply divide it by 60 which is 0.3 hence our answer is 0.3miles/hour
