Answer: 2.87 hours
Step-by-step explanation:
There may be a typo in the question because 55 hours in a day is not logical so you must have meant 5.5 hours.
In that case, the hours he will require on the third day would require the distance left to calculate. Get this distance from the first 2 days.
Day 1 distance travelled = Time * Speed
= 5.5 * 66
= 363 miles
Day 2 distance travelled = Time * Speed
= 5.5 * 58
= 319 miles
Total distance remaining
:= 840 - 363 - 319
= 158 miles
Travelling at 55 miles per hour, the time to be taken is:
= Distance remaining / Speed
= 158 / 55
= 2.87 miles per hour
Answer:
1. -370
2. 70
3. 10.75
4. 6700
5. 37.26
Step-by-step explanation:
1. Estimating the solution means round the numbers to the nearest ten, then subtract the rounded numbers.
2. Same thing as #1
3. Using long division, it should be quite easy. If you need more evaluation, comment and I'll answer.
4. To the nearest hundred, you write the closest exact hundred. example: 8334 would be rounded to 8300.
5. To the nearest hundredth, you write the closest exact hundredth. example: 65.734 would be rounded to 65.73
Hope this helped, good luck!
