Answer:80
Step-by-step explanation: if you do 45:100% and then x36 you get the result
So one hour is 60 minutes,
5/6 of an hour would be, 50 minutes. Basically 60/6=10 and 10*5=50
so if the robot does 8 tasks in 50 minutes and each tasks takes the same amount, the equation would be 50/8
50/8= 6.25
Each task is 6 minutes and 25 seconds.
in the like term you can add directly and make it single fraction and in unlike term you have to take LCM of denominator .
Answer:
1) 3:15 hours.
2) 68 km per hour.
Step-by-step explanation:
Since a bus from Nantes at 3:50 p.m. and arrives at Tours at 7:05 p.m. after having traveled 221km, to calculate the journey time in hours and minutes and calculate the average speed of this bus, the following calculations must be performed:
1) 7:05 - 3:50 = 3:15
Thus, the duration of the trip was 3 hours and 15 minutes
2) 0:15 = 0.25
221 / 3.25 = X
68 = X
Thus, the average speed of the bus was 68 km per hour.
