Time = t = ?
Distance 1 = d1 = 224 miles
Distance 2 = d2 = 175 miles
speed1 = v1 = d1/t
speed2 = v2 = d2/t
Also, speed 1 = 14 + v2 (Given in the data)
OR speed 1 = 14 + d2/t
speed 1 = 14 + 175/t
224/t = 14 + 175/t
multiplying both sides (each term) by "t" we get
224 = 14t +175
OR 14t = 49
t = 3.5 hours
now, speed of 1st car = 224 miles / 3.5 hours
= 64 miles / hour
and speed of 2nd car = 175 miles / 3.5 hours
= 50 miles/ hour
Answer:

<u>Answer:</u>
- 80 km is 9% of 888.89 km.
<u>Step-by-step explanation:</u>
<u>We know that:</u>
<u>Work:</u>
- 80/9 km = 1%
- => 80/9 x 100 = 100%
- => 8000/9 = 100%
- => 888.89 km = 100% (Rounded to nearest hundredth)
Hence, <u>80 km is 9% of 888.89 km.</u>
Hoped this helped.
