Answer:
the cyclists rode at 35 mph
Step-by-step explanation:
Assuming that the cyclists stopped, and accelerated instantaneously at the same speed than before but in opposite direction , then
distance= speed*time
since the cyclists and the train reaches the end of the tunnel at the same time and denoting L as the length of the tunnel :
time = distance covered by cyclists / speed of cyclists = distance covered by train / speed of the train
thus denoting v as the speed of the cyclists :
7/8*L / v = L / 40 mph
v = 7/8 * 40 mph = 35 mph
v= 35 mph
thus the cyclists rode at 35 mph
Well if you want to simplify you can do it to ways
1 leave it how it is because you cant simplify anymore
or
2 turn it into a mixed number
first see how many times you can fit 8 into 27
8*2=16 8*3=24 8*4=32
so it is 3 times
and you have 3 left over so that goes over 8 and your simplification is 3 3/8

Answer:
64/8
Step-by-step explanation: If a = 32 and b = 8, then the fraction turns into 2(32)/8.
2*32 is 64.
So, it turns into 64/8
You could also simplify it to 8/1, which is 8.
Answer:
h < -3
Step-by-step explanation:
2 < -19 -7h
or 19 + 2 < -7h
or 21 < -7h
or 21/(-7) > h [flip the sign when dividing with negative Number ]
∴ -3 > h ( h < -3 )
