Using proportions, it is found that:
- Peter is walking at a rate of 3 km/h.
- MJ is biking at a rate of 9 km/h.
---------------------------
- Peter is walking at a rate of x km/h.
- MJ is biking 6 km/h faster than Peter, thus 6 + x km/h.
- Opposite directions, thus, their distance increases at a rate of (6 + 2x) km each hour, as
.
6 + 2x km each hour, 18 km after 1.5 hours, thus, the rule of three is:
1h - (6 + 2x) km
1.5h - 18 km
Applying cross multiplication:






Then:
- Peter is walking at a rate of 3 km/h.
- MJ is biking at a rate of 9 km/h.

Answer:
120 divided by 10 is 12 yards per completion
Answer:
12 is the correct answer
Step-by-step explanation:
1) so whenever we're dividing with fractions we need to change the division sign to multiplication and turn the second fraction upside down (reciprocal)
so
6*2/1=12
Julio did change the division sign to multiplication but he forgot to take the reciprocal of the second fraction (he left the second fraction as is)
what Julio did: 6*1/2=3
Hope this helps!
