jekas [21]
For this case, the first thing you should know is:
 d: v * t
 Where,
 d: distance
 v: speed
 t: time
 To go to school by bus we have:
 d = 45 * t
 To return from school we have:
 d = 2.5 * (1-t)
 how the distance is the same:45 * t = 2.5 * (1-t)
 Answer:
 the equation that will help find the time it takes chelsea to get to school on the bus is:
 45 * t = 2.5 * (1-t)
 Note: the equation will have one solution.

How many whole numbers greater than 0 and less than 100 are divisible by 2? ​
Bess [88]

Answer: 49

Step-by-step explanation:

If it's less than 100, that means that you can't use the number 100 in the answer. From 0 - 100 there are 50 even numbers (divisible by 2), so that means that there would be 50 - 1 even numbers between 0 and 100 (not including 100). 50 - 1 = 49

:D
