Answer: 63.75 = 85h
Solving gives 0.75 hours.
Step-by-step explanation:
we now that speed = distance / time
therefore time will be Distance / speed
Given that distance = 63.75miles
Speed= 6=85miles per hour
Time(h) = 63.75miles/ 85.---- equation 1
But from the options given, the equation that can also be used to find number of hours is
63.75 = 85h
such that making h subject of formula still give us
h= 63.75/85 as in equation 1 above
solving gives that Time ( h) = 0.75 hours .
Answer:
30 kilometers
Step-by-step explanation:
40 min=2/3 hour
2/3*45=30
Answer:
t≤ 8/5
Step-by-step explanation:
-4t≥-2/5 (at last means greater than or equal to }
multiplying by -1
when we multiply or divide by negative number sign of inequality changes
4t≤2/5
t≤4(2/5)
t≤ 8/5
Answer:
