Answer:
1. 2.5 hours
2. 70km
3. 1 hour
4. 60km
5. 7
Step-by-step explanation:
I'm not that sure with number 4 but this is the solution of the answer
40km = 30minutes
+
20km = 15 minutes
=
60km = 45 minutes
In 45 minutes at an average of 80km/h the vehicle will travel 60km
Here's the formula for 5 cuz it's kinda complicated
Ex:
What is your rate of speed? Use the formula r = d/t. Your rate is 24 miles divided by 2 hours, so: r = 24 miles ÷ 2 hours = 12 miles per hour
So 245km divided by 3.5hr = 7
It's up to you if you consider this answer
