The gap between Hassan and chinedu is 7m 21cm, while the gap between chinedu and salewa is 6m 32cm. What is the gap between Hassan and salewa, if the three pupils are on the straight line

Answer 1

To find the gap between Hassan and Salewa, we need to add the gaps between Hassan and Chinedu and Chinedu and Salewa together.

1. Convert the measurements into the same unit (meters and centimeters):

   • The gap between Hassan and Chinedu is 7 m 21 cm.
   • The gap between Chinedu and Salewa is 6 m 32 cm.

2. First, convert both gaps into centimeters:

   • For Hassan and Chinedu: \[ 7 \text{ m} = 700 \text{ cm} \quad (\text{since } 1 \text{ m} = 100 \text{ cm}) \] \[ \text{Total} = 700 \text{ cm} + 21 \text{ cm} = 721 \text{ cm} \]

   • For Chinedu and Salewa: \[ 6 \text{ m} = 600 \text{ cm} \] \[ \text{Total} = 600 \text{ cm} + 32 \text{ cm} = 632 \text{ cm} \]

3. Now, add the two gaps together: \[ \text{Gap between Hassan and Salewa} = 721 \text{ cm} + 632 \text{ cm} = 1353 \text{ cm} \]

4. Finally, convert the total back to meters and centimeters: \[ 1353 \text{ cm} = 13 \text{ m} , 53 \text{ cm} \quad (\text{since } 100 \text{ cm} = 1 \text{ m}) \]

Thus, the gap between Hassan and Salewa is 13 m 53 cm.
