Question

1. Some roads in Poland have a speed limit of 140 km/h. How fast is this in miles per minute?

Answer 1

I only know number one here you goSolution
Conversion for Km to Miles
1km = 0.621 miles

Conversion Hours to minutes
1 hr = 60 mins

solve
140 (0.621 miles / 60 mins )
= 140 (0.01035 miles/min)
= 1.449 miles/min

Answer 2

1. 140km/1hour | 140(0.621mi/60min) = 0.01035 miles/min

2. 320,000Riels/1month divided by $4,000/1month = $80/month times 12 months/1year =$960/1 year

3. 180,000euros/1year times $1.36/1year = $244,800/1year divided 365days/1year = about $670.68/1 day

4. 3oz/1day times 7days/1week = 21oz/1week divided by 16oz/1week = 1.3125lbs/1week

6. 120km/1hour times 1000m/60minutes = 120,000m/60minutes divided each side by 60 = 2,000m/1minute times 3.28084feet/60seconds = 6561.68/60seconds divided by 60/60 = about 109.36 feet/1 second

7. 500inches/1year times 2.54cm/1year = 1270/1year divided by 365days/1year = about 3.48 cm/1 day
