Explanation

Time = 19 ÷ 57 = 1/3 hour

Distance at 110 km/h = 110 × 1/3 = 36.67 km

Explanation

Rate = distance / time  

Distance = 500 m = 0.5 km  

Time = 50 min = 50/60 hr = 5/6 hr  

Speed = 0.5 ÷ (5/6) = 0.5 × 6/5 = 3/5 = 0.6 km/hr

Explanation

 Given:

6 men × 8 hours/day = total man-hours per day = 48 man-hours

They earn Rs. 720 per week

Now:

8 men × 6 hours/day = 48 man-hours per day — same total man-hours as before

So, since the total man-hours per day (and thus per week) are the same, the weekly earnings will also be the same.

Explanation

Total distance = 225 + 370 = 595 km

Total time = 3.5 + 5 = 8.5 hours

Average speed = 595/8.5 = 70 km/h

Explanation

Step 1: Find baskets per hour

Baskets per hour=1/2/31​=1×3​/2=3/2​ baskets per hour

Step 2: Multiply by total time (7.5 hours)

Baskets in 7.5 hours=3/2​​×7.5=3/2​​×15​/2=45 /4 ​ baskets

Explanation

Step 1: A’s 1-day work

A=1/10​ of work per day

Step 2: A + B’s 1-day work

A+B= 1/8​ of work per day

Step 3: B’s 1-day work

B=(A+B)−A=1/8−1/10​

Find LCM of 8 and 10 = 40:

1/8​=5/40​,1/10​=4/40​
B=5/40​−4/40​=1/40 of work per day

Step 4: Days B alone will take

Days= 1/B’s 1-day work​=1/1/40​=40 days
